Specification of Letters Patent. i 1;lter1{e(DC. 30, 1.913.

Application led Decemer. 1912. Serial No. 739,196.

To all lwhom it may concern Be it known that I, JOHN HIST, a resident of Alliance, county of Stark, and State of Ohio, have invented a new and useful Improvement in Lan'd Rollersor Pulveriecrs, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an end view of one form of my improved pulverizer; Fig. 2 is a plan view of the pulverizing rollers, together with their journals the supports being sectioned on the line II--II of Fig. l; Fig. 3 is a sectional view on the line III- Hl of Fig. 2, through the journal for the shafts of two ot' the rollers; Fig. 4. is a sectional view on the line lV-IV of Fig. 3; and Fig. a sectional view on the line V-V of Fig. 2 through the journal frames for the ends of the shafts of the rollers.

This invention relates to land rollersv or pulverizers, and is designed to provide' a cheap and eiiicient device of this character, which `is provided with a plurality of sets ot' rolls in transverse alinement with each other, each of which is adapted to-oscillat-e independently of the other rollers, so that all of the rollers will be in contact with the ground throughout their lengths when going over uneven surfaces. A

The precise nature of my invention will be best understood by reference to theaccompanying drawings, which will now lbe described, it being premised, however, that various changes may be made in the details ot' construction and general arrangement of lthe parts, without departing from the spirit and Scope of my invention, as defined in the appended claims.

ln the drawings, the numeral 2 designates the longitudinal angle bars on the main or supporting frame, the ends of which 'are secured Ito frames or brackets 3. The lower ends of these brackets 3 engage pins Al, which are connected to forked projections 5, which extend upwardly from journal brackets 6. The pulverizer comprises tour` rollers 7, each of which is provided with a shaft 8,

two of the shafts being jouinaled in one bracket 6, `while the other shafts aresjejcured in the other bracket 6, as can "be seen 'by reference to Fig. 2. The shafts 8 engage the journal brackets 6 at-alpoint slightly bevond4 the central portion thereof, the inner ends of the shafts of one set of rollers being journaled in a journal frame 9, while the inner ends of the other set are journaled in a similar frame t) in engagement with the other frame 9 at the central portion thereof. The engaging portions of these frames 9 are convened` as indicated at 9a; the radii of which are struck from about the center of the journal frames G, so that the journal frames 9 will be in contact with each other when the various rollers are rocked Winn passing over an uneven surface. i

Connected to the angle bars 2 and extending at right angles thereto is ajpole or tongue 10.

ll is a draft bar bracket connected to the under side of the pole andextending downwardly therefrom in advance of the rollers,-

and 12 are draft bars which are pivoted at one end to the bracket ll, and at the other end to the journal frames 9.

It will be readily understood by those familiar with theart that when the pulverizer passes over uneven ground, the rollers 7, 7 at one end may assume an angular position with relation to the rollers at the. other end, and at the same time'each of the rollers at either end can assume different vertical positions with relation to each other.v Also that the shafts will have draftconnections at two points with the frame and tongue, so that. the shafts vof the rollers will always be in a position to permit the rollers to rotate there m, or to permit the 'shafts to rotate in their journals.

The advantages of my invention result from the provision of a plurality of sets of rollersl in which the shafts ot' all the rollers are connected to journal bracket-s and frames, which are connected to the main frame in such a manner that the rollers atone end of the main frame can assumev an angular position with relation to the rollers at the other end of the main frame, and at the same time maintain thc axes of the shafts of the rollers at one end of the frame in approximately the same vertical planes as the axes of thev shafts of the rollers at the other end of the main frame and further, from the provision of means for permitting the shafts of the rollers at one end of the frame to assume dil'erent vertical positions with relation to the other shaft atl the same extending on both sides thereof, rollers on ,maintain tlie'sbafts atI both ends of the@ 2. A piilverizer having a main frame, a downwardly extending bracket connected to each end of the main frame, a second bracket of the first mentioned end of the frame, and at tbe suine time] frame in approximatelyv the same vertical planes. swiveled to each I claim bracketsha pair of shafts mounted in each l. A pulverizer having a main frame ot' I of said second brackets and extendingonbotb approximately rectangular form, a downsides thereof, rollers on both ends of eacli of said shafts', a tongue connected to the wardly extending bracket rigidly connected A man1 frame, a downwardly extending draft to each end of the main frame, a bracket pivotally connected to 'each ot' the first mentioned brackets, a plurality of roller shafts mounted in each of said second brackets and member connected to the tongue, a second bracket connected to the inner ends of each pair of shafts, and a link connected to each of said last mentioned bracketsv and 'the downwardly extending draft member on the as described.

have hereunto set each end of each of said shafts, a second bracket connected to the inner ends of each tongue; substantially set of slialts, the bracket on one set of shafts l In testimony whereof, I
